The first battle !!

The setting sun cast a warm, golden glow over the Uchiha training grounds, signaling the end of another day of intense practice. Kazuki Uchiha, now five years old, was diligently working on his hand signs, his small fingers moving with a mix of determination and concentration. His uncle, Kagami Uchiha, stood nearby, observing with a mix of pride and patience. Kazuki's mother, always supportive, watched from the sidelines while baby Shisui lay on a blanket, his wide eyes tracking Kazuki's every move.

Kagami began by demonstrating the necessary hand signs for the Uchiha clan's fire techniques. He started with the **Boar** sign: his left hand formed a tight fist with the thumb pressing against the base of the index finger and the remaining fingers curled inward, resembling a boar's snout. Next was the **Serpent** sign, where his fingers twisted and intertwined, mimicking the sinuous movement of a serpent, with the index and middle fingers forming a complex spiral. Finally, Kagami performed the **Tiger** sign by extending his fingers outward, each digit splayed wide like the claws of a tiger.

Kazuki watched intently, his eyes fixed on the precise movements. He tried to replicate the Boar sign, curling his fingers into a fist and adjusting his thumb. The Serpent sign proved more challenging; Kazuki's fingers twisted awkwardly as he attempted to mimic the serpentine motion. Finally, he extended his fingers to form the Tiger sign, though they trembled slightly from the effort. Despite the difficulty, Kazuki persisted, his determination unwavering.

The intricacy of these hand signs was not lost on Kazuki. Each sign required a specific configuration of the fingers, each movement calculated to channel chakra correctly. The **Boar** sign involved a precise curling of the fingers into a fist, aligning the thumb against the base of the index finger to create a firm, compact shape. The **Serpent** sign was a dance of the fingers, where the index and middle fingers twisted to create a sinuous spiral, demanding coordination and dexterity. The **Tiger** sign required the fingers to stretch outward, the open palm forming a broad, sweeping motion, reminiscent of a tiger's claws.

Kazuki struggled with the control of his chakra. Channeling chakra through his fingers felt like trying to move thick, viscous sludge through his veins. Each hand sign required meticulous control, his focus trained on the flow of energy as it navigated the pathways of his body. The sensation was both foreign and exhausting, as if every muscle in his hand was resisting the flow of his chakra. Kazuki could feel his chakra fluctuating, sometimes overloading and other times faltering, as he tried to maintain the precision required for the jutsu.

Kagami guided Kazuki through the Uchiha clan's fire techniques. The first was the **Fireball Jutsu**. Kazuki took a deep breath and focused his chakra, performing the hand signs with a concentrated effort. A flicker of flame sputtered from his mouth, gradually growing into a fireball that illuminated the twilight. The sight, though modest, filled Kazuki with a sense of accomplishment. He could feel the heat of the flames against his face, a tangible reward for his efforts.

Next came the **Fire Phoenix Jutsu**. This technique required Kazuki to release multiple small fireballs, each resembling a phoenix's fiery plumage. The hand signs remained the same, but the technique demanded fine control of chakra. Kazuki's initial attempts produced erratic bursts of flame, but with practice, he learned to create a flurry of fireballs that danced across the training field. Each small fireball had to be meticulously controlled, requiring Kazuki to balance his chakra output carefully to avoid them merging into a single, uncontrollable blaze.

The final technique was the **Great Fireball Jutsu**. This advanced jutsu required additional hand signs, including the **Dragon** and **Hare** signs. The Dragon sign involved forming a sharp, angular shape with the hands, while the Hare sign required a compact, rounded gesture. Combining these with the previous signs, Kazuki generated a massive fireball that roared with intensity, casting a bright, fiery glow that contrasted with the encroaching night. The sheer size of the fireball required a massive concentration of chakra, making Kazuki's hands tremble under the strain.

As Kazuki took a break, Shisui, still on his blanket, squealed with excitement. "You're doing great, Kazuki! Keep it up!" His tiny hands flailed in encouragement, and his innocent eyes shone with admiration.

The peaceful training session was interrupted when three-year-old Kakashi Hatake bounded into the field with an eager grin. "Hey Kazuki, I want to see how much you've improved!" he declared, his eyes gleaming with competitive spirit.

Kazuki looked up, a mix of surprise and curiosity in his eyes. "Are you sure, Kakashi? I've been practicing a lot."

Kakashi's grin widened. "Yeah, let's have a friendly match. I want to see what you've got!"

As Kakashi prepared to challenge Kazuki, Shisui, who had been watching with wide eyes, stood up and approached Kakashi. "I want to fight too! I've been practicing!"

Kagami stepped in, his expression firm yet encouraging. "Shisui, you're still too young and not yet skilled enough to fight. You'll need to wait until you're older and more experienced."

Shisui's enthusiasm dimmed, and he quietly pouted as he sat back down, his small shoulders slumping in disappointment. He muttered, "Okay," and watched the scene unfold with a resigned sigh.

With Shisui's challenge deferred, Kazuki and Kakashi prepared for their friendly duel. Kazuki took a fighting stance, his posture low and balanced, his weight centered. Kakashi mirrored him, his eyes locked on Kazuki, his grin widening in anticipation.

The match began with a flurry of action. Kakashi charged forward, unleashing a series of quick punches aimed at Kazuki's torso. Kazuki dodged and countered with a precise elbow strike to Kakashi's side. Kakashi stepped back, but quickly closed the distance, aiming a high kick toward Kazuki's head. Kazuki blocked the kick with his forearm, the impact jarring but manageable.

Kazuki saw an opening and executed a front kick, driving Kakashi backward. The force of the kick sent Kakashi sprawling onto the grass. Kakashi quickly rolled to his feet, his eyes bright with determination. "Not bad! But I'm just getting started!"

Kakashi leaped into the air, performing a spinning kick aimed at Kazuki's head. Kazuki ducked under the kick and sidestepped, his foot making contact with Kakashi's thigh in a powerful side kick. Kakashi grinned through the pain and threw a shuriken towards Kazuki. Kazuki, reacting with reflexive agility, deflected the shuriken with a swift upward block with his own kunai.

Kazuki charged forward, closing the distance between them. He executed a series of rapid punches and low kicks. Kakashi countered with nimble footwork, weaving around Kazuki's attacks. Kazuki feigned a right hook and instead delivered a quick knee to Kakashi's midsection, forcing him to double over. Kazuki then pulled Kakashi's arm, using it to leverage a throw that sent Kakashi tumbling to the ground.

Kakashi quickly rolled to his feet, his grin unwavering. "You're really good, Kazuki. But let's see if you can handle this!"

Kakashi launched into a series of acrobatic moves, including a high kick followed by a backflip. Kazuki, matching his agility, blocked Kakashi's high kick and attempted to follow up with a spinning kick. Kakashi ducked and countered with a well-timed front kick that pushed Kazuki back a few steps, disrupting his balance.

Kazuki, determined, took a deep breath and executed a series of rapid, powerful punches, each strike delivered with precision. Kakashi, though skilled, struggled to keep up with Kazuki's relentless assault. Kazuki saw an opening and dashed forward, performing a spinning elbow strike that caught Kakashi off-guard, sending him staggering back.

Breathing heavily, Kazuki saw his chance. He launched into a series of precise kicks and punches, aiming for Kakashi's upper body and legs. Kakashi, though agile, found it increasingly difficult to defend against Kazuki's barrage. Kazuki executed a high spinning kick aimed at Kakashi's head. Kakashi ducked and reached out to catch Kazuki's foot, but Kazuki's reflexes were swift. With a smooth swish motion, he brought this foot down into a heavy ax kick on Kakashi shoulder.

Kakashi was sent stumbling, Clutching his neck but quickly regained his balance. He laughed, his eyes gleaming with admiration. "That was awesome, Kazuki! You've really improved!"

Kazuki, breathing heavily, extended a hand to Kakashi. "Good match," he said, his grin matching Kakashi's.

As the sun dipped below the horizon, the training ground was filled with a sense of camaraderie and accomplishment. Kazuki, despite the challenges and the harsh realities of the world he lived in, felt a deep satisfaction. The friendly rivalry with Kakashi and the support from his family reminded him of the progress he had made and the promising future ahead.
